A process for setting a retrieval window used for finding an object surely and quickly by an image processing equipment. Using a reference point G as a center, which is located in a group of sampled detection points Pi, the coordinates of the points Pi are determined in succession anticlockwise. In this order, stored are the coordinates data Qi of the points Pi in a file (S1-S9), and the coordinat...

Digital signals, such as digitized television signals, are subjected to a source coding step followed by a channel mapping step. The source coding step causes the television signal to be represented by two or more data streams while, in the channel mapping step, the mapping is such that the data elements of the various data streams have differing probabilities of being erroneously detected at the ...

The method of extracting a contour involves obtaining a potential image by multi-fractal analysis of a base image. Each element of the potential image is represented by one local fractal dimension adjacent to a pixel which corresponds to the base image. The local fractal dimension is an estimate of a Holder coefficient. The coefficient is calculated using a multi-fractal measure from a count in di...

A resilient, elastic self-expanding prosthesis comprising a flexible tubular body, the diameter of which is variable under axial movement of the ends of the body relative to each other, said body being composed of several individual rigid but resiliently flexible thread elements with spring properties each of which extends in helix configuration with the center line of the body as a common axis, a...

The photoresist films 45,46 to be laminated onto the base 26 are ...

The cage (I), which is osteo-permeable and osteo-conducting, is trapezoid in shape and designed to fit between the fractured head of the humerus and an intermediate insert (II) fitted into the metaphysis canal. The upper surface of the cage has spikes (1) which engage with the head of the humerus, while its under surface has a projection (2) to engage with the metal intermediate insert (II). The w...

The invention relates to a finger joint prosthesis comprising a first part (10) provided with a female block (13) hinged to a second part (20) provided with a male block (23) by means of a hinged-pin (4). An internal ring (3) and external rings (1, 2) mounted on the blocks provide for movements with reduced frictions with the hinged-pin (4). Clearances, particularly between external rings (1, 2) a...

A needleless jet injection device including a barrel (1) fitted with a cap (3) at one (4) of the ends thereof (4, 5). Relative motion of the cap components actuates a setting device (2) operably connected to a percussive member. A cartridge (28) arranged at the other end (5) of the barrel (1) comprises two elements (49, 50), i.e. a first element (49) forming a container for the active principle, a...

The joint consists of a spherical head (10) which fits without play into a hemispherical cavity (20) which has a transverse partition (3) projecting from its base. The upper edge (30) of the partition is straight and lies perpendicular to the axis of the cavity, while the end of the spherical head has a slot (11) with a width at least equal to that of the partition and a depth at least as great as...
